2 Claim. (01. m-u) This invention relates to improvements in supportsfor horizontal cylindrical tanks and method of erecting the same.

Considerable attention has been given to the question of proper supportsfor tanks of the character referred to. Heretofore, such supports haveincluded a relatively large number of saddles fairly closely spacedunder the tank. Any saddles underneath the tank introduce quite severelocal stresses.

The particular feature of my inventionis the provision of supports forhorizontal cylindrical tanks which do away entirely with saddles underthe tank. I provide supports which are attached to the tank at the endsonly. I have found that the head of a cylindrical tank ordinarily isstrong enough to hold the tank in its true cylindrical shape. I havefound that when the heads are strong enough to hold the tank in its trueshape, the spacing of supports for the same can be increased so thatonly two supports need be employed, one at each end of the tank.

By using only two supports, one at each end of the tank, it is possibleto effect not only a saving in weight, but also a saving in the cost ofthe foundations upon which the supports rest.

Another feature of my invention is the pro-- vision of a support whichis of assistance in reducing the cost of elevating the tank to theproper height.

Other features and advantages of my invention will appear more fully asI proceed with specification.

In those forms of devices embodying the iea tures of my invention shownin the accompanying drawings Figure l is a view in side elevation oi acylin drical tank employing my improved supports; Fig. 2 is a similarview in end elevation; Figs. 3 and 4 are views similar to Figs. 1 andit, re spectively, showing a modification; Fig. 5 is a view similar toFig. 4 showing another modifies tion; Figs. 6 and 7 are views similar toFigs. 1 and 2, respectively, showing another modihcation; Figs. 8 and 9are views similar to Figs. 1 and 2, respectively, showing anothermodiiication; Figs. 10 (fragmentary) and ii are views similar to Figs. 1and 2, respectively, showing another modification; Figs. 12 and it areviews similar to Figs. 1 and 2, respectiveiy, showing anothermodification; Fig. it is a view in end elevation showing anothermodification; id is a fragmentary view in side elevation oi the deviceof Fig. it; Fig. 16 is a view similar to Fig. 14 showing the method ofelevating the their upper ends attached to the head of the tank; Fig. 17is a view taken as indicated by the line '1'! of Fig. 14; Fig. 18 is aview taken as indicated by the line 18 of Fig. 14; Fig. 19 is a viewtaken as' indicated by the line 19" of Fig. 14; and Fig. 20 is a viewsimilar to Fig. 15 with parts broken away.

As shown in the drawings, the exact details of the support may varyconsiderably, the general principles being retained.

In Figs. 1 and 2, the cylindrical tank is indicated by 10 and the headsby 10. At each end the support comprises an A-frame including the twouprights 11, 11 with their upper ends connected together by a plate 12.13 indicates thecross brace. The members 11 and'13 may be of anysuitable material, for example, angle irons. The lower ends of theuprights or legs 11 may rest upon suitable concrete foundations 1t, 14.The upper portions of the uprights or legs 11 are attached to the heads10 in any suitable manner, as, ior example, by welding. Preferably, theattachment should extend through the major portion of the leg or uprightthat lies adjacent to or contacts with the head of the tank.

In the construction of Figs. 3 and 4, the tank is indicated by 110 andthe heads by 110. In this form, instead of employing an A-irame at eachend, I use a pair of uprights 111, 111 with and their lower ends restingupon a suitable idati 11d.

The iorm of Fig. 5 is substantially the e as that shown in Fig. 4,except that the uprights 211 at each end oi" the t are slanted towardeach other so that they meet at the bottom edge oi the tanh. Front thispoint they lie parallel and acent to each other and extend entireiyacross the head thi oi the tank. The paraiiel portions, as indicated by211 are attached to the head 210 and the lower ends oi the legs hi1 restupon the ioundation 21d.

The to oi Figs. 6 and 7 is substantially the. same as that shownin Figs.3 and 4., except that the tanir did is provided with rounded heads 31d.@onse uently, the upper portions of the uprights tit are rounded, asindicated by til where they are attached to the head 31c. 314 indicatesthe ioundation.

' in the form of Figs. 3 and 9, the tank 410 is also provided withrounded heads this. In this form, however, the upper ends 411 of theuprights tit are not attached directly to the head hut are attached tothe cylindrical portion of the tauh at its extreme end. Accordingly,they Mil) ' lower ends of the supports are indicated by s11 and theirbottom ends rest upon the foundations 514.

In Figs. 12 and 13, I have shown a cylindrical tank 610 with flat heads810 and have provided supports designed to permit easy and quickerection of the tank thereon. In the form here shown, the supportingmembers are indicated by 611, there being a pair at each end of thetank. Prior to erection the tank is laid on the ground or floor at oneside of its permanent location, as indicated by broken lines in Fig. 13.The lower ends of the members 611 at each end of the tank are pivotallyattached to a suitable base or foundation member 614, the pivot pointsbeing indicated by a and b, respectively. At each end of the tank, theupper end 01! one of the members 611 is pivotally attached to the headoil the tank substantially at the top of said head,

as indicated by c. The other memmr is pivotally attached to the head atone side oi the bottom of said head, as indicated by d.

The structure is then in the position shown by the broken lines in Fig.13. From this point the remote ends of the more oil on the ground'areraised, the various p pivoting on the centers u, b, c and d. we iscorrtinued until the upper en oi the members 611 come together, asindicated by the solid lines in Fig. 13, whereupon the bolts e and f areplaced in position to fo a rigid permanent support for the tank.

In the structure oi Figs. id to 2d, inclusive, the tank is indicated by"lid and pded with flat heads lic hit each end oi the t it provide apair of spaced vertical suppo v bers C, C, each provided with a seriesof holes 715. The tank hwd is provided with angle irons base orfoundation member- 714. e oi the boltsv 718 is then inserted at each endend the tank rocked ciently to place the other bolt at each end in thenext higher hole in the other upright C. The lower bolts are then takenout and the t rocked in the other direction and the bolts replaced inthe next higher hole. in er,

the tank is rocked or walkedi' upwardly until the desired height isreached. Therocldng of the tank may be facilitated by attaching themembers J and K to the tank, as shown in'Fig. 16, to give the desiredleverage. During this raising, the members L may be employed, asindicated by the broken lines in Fig. 15.

After the tank has been raised to the desired height, the members L areplaced in the position shown in Fig. 14 and. as indicated by the solid 1lines in Fig. 15. Diagonal members are also put in place at each end ofthe tank to give additional support. As here shown, these diagonalmembers are formed of double angle irons. The upper portion of eachlying adjacent the head is indicated by D, B and the lower portion, D,J. After thetank is raised, I preferto-put in place uprights K, K underthe uprights A, A on each head, said members K, K lying next to thelower portions of the uprights C and forming virtually continuations ofthe members A, A on the head.

The member 114 may rest on plates E. Suitable splice plates M may beemployed for fastening together abutting ends of supporting members, forexample, the abutting ends of the members D and D.

Where the supporting members at the end of the tank have a considerableportion of their length attached to the head of the tank, suchattachment may assist in stiffening the head.

While I have shown and described certain embodiments of my invention, itis to belunderstood that it is capable of many modifications. "is es,therefore, in the construction and arrangement may be made withoutdeparting from the spirit and scope of the invention as disclosed in theappended claims, in which it is my intention to claim all noveltyinherent in my invention es broadly as permissible, in view of the priorart.

What I regard as new, and desire to secure by Letters Eatent, is:

l. In combination with a horizontal cylindrical tanlr having heads, apair of spaced vertical supporting members at each end thereof providedwith a series of holes, securing means on each head or the tank, andmeans for detachably securing said securing means first to one supportof each pair and then to the other, said securing means cooperating withthe holes in said supporting members, whereby the tank can be elevatedby rocking the same on said summits.

2. In combination with a horizontal cylindrical tank having heads,supporting means at each end thereof, each provided with two verticalspaced rows of holes, securing means secured on each head of the tank,and means for detachably securing said securing means successively firstto one of the holes of one row in each supporting means'and then to oneof the holes of the other row, whereby the tank can be elevated byrockmg the same on said supporting means.
